5. Cleaning and Maintenance
1. Disconnect the device from the mains prior to maintenance activities.
1. The power supply cables must not show any damage. Have a qualified technician
maintain the device.
2. Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
3. There are no user-serviceable parts, apart from the fuse. Contact your dealer for spare
parts if necessary.
4. Store the device in a dry, well-ventilated, dust-free room.
Replacing the Fuse
1 Only replace the fuse by a fuse of the same type and rating.
1 Before replacing the fuse, unplug the mains lead.
2 Wedge the fuse holder out of its housing with a flat-head screwdriver.
3 Remove the damaged fuse from its holder and replace with the exact same type of fuse.
4 Insert the fuse holder back in its place and reconnect power.
